Reflectometry is a general term for the use of the reflection of waves or pulses at surfaces and interfaces to detect or characterize objects, sometimes to detect anomalies as in fault detection and …

Reflectometers are instruments for measuring the reflectance (or reflectivity) of objects, i.e., the fraction of the incident optical power which is reflected.

Feb 28, 2025 · Reflectometers are essential instruments used to measure the reflectance of objects, particularly the fraction of incident light that is reflected off a surface. Optical reflectometers operate …

Jun 3, 2010 · A reflectometer used by Hunter [2], originally designed by F. S. Johnson, consists of a steel cylinder separating two flat plates. Each cylinder end and each plate has matching V-grooves …

Dec 18, 2025 · Reflectometry provides measurements of thin film thickness, density, and roughness, and is used in applications such as semiconductor devices, optical coatings, magnetic layers, and …

The polarization of light during oblique incidence is significant in reflectometer measurements. Instruments may use linearly polarized or unpolarized light, with some accommodating defined …

Photometry measures light absorption for analyte quantification, while reflectometry determines surface characteristics like color.
